That is a lovely elephant and I'm very pleased to see one similar to mine (I own the white Murano glass elephant you mention in your opening post). I only made an educated guess as to its attribution. Looking at the characteristics of your elephant such as the recessed feet and tusks, these are definitely similar if not identical to mine. There are differences too however, such as the eyes, the segmented trunk and the tail, which on my elephant is attached to the leg and clipped. Perhaps they have a common maker, most likely we'll never know.
The white and gold elephant shown on Anita's Murano Zoo is now displayed on the Moltabellaglass website (display only, not for sale). The black elephant she mentions is sitting on a shelf in front of me and I never cease to marvel at this little Murano art glass masterpiece (thanks Anita!). Anita and I had many discussions in the past about these two elephants so I'm very interested to read she now thinks it may be VAMSA.
